Description

Technical Field

[0001] This application belongs to the technical field of coatings, and in particular relates to a container for coatings. Background Technology

[0002] During the storage and transportation of paint, airtightness is crucial for paint containers. Currently, common paint containers on the market mainly consist of a container body and a container lid, which are usually connected by threads or snaps.

[0003] However, existing paint containers have significant shortcomings in terms of sealing. While threaded connections can achieve a degree of sealing, gaps between the threads allow moisture and air to enter. Especially during long-term storage, moisture from the air can seep in through these gaps, causing the paint to become damp and deteriorate, affecting its performance and quality. For paint containers with snap-fit ​​connections, these snaps may loosen over time or due to external impacts, leading to seal failure. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this application is to provide a container for coatings that can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a container for coatings, comprising:

[0006] The cylindrical body has an internal cavity and an opening at the top;

[0007] A cylinder cover, disposed on the cylinder body and used to seal the opening, includes a first sealing body and a second sealing body;

[0008] The first sealing body is used to seal the opening, and the second sealing body is used to seal the first sealing body.

[0009] The coating container described above employs a dual-sealing design: a first sealing body directly seals the opening of the cylinder, and a second sealing body further seals the first. Compared to existing single-seal methods such as threads or snap-fit ​​seals, this significantly improves the container's sealing performance and effectively solves the problem of easy failure of single-seal structures in existing coating containers. Compared to traditional containers relying solely on single-layer seals of threads or snap-fits, this dual-layer protection system prevents the initial intrusion of impurities with the first sealing body, while the second sealing body reinforces the first. The two layers function independently yet work synergistically, significantly enhancing the container's ability to resist external moisture, air penetration, and leakage of volatile coating components during long-term storage or transportation. Furthermore, a handle is installed on the cylinder.

[0010] Furthermore, the first sealing body includes:

[0011] A convex ring is provided on the cylinder, and an inwardly protruding mounting step is provided on its inner wall, and an internal thread is provided on the mounting step;

[0012] The first cover includes a sealing part and a connecting part. The connecting part is cylindrical and has an external thread on its outer wall that is adapted to the mounting step.

[0013] The sealing part and the connecting part are an integral structure.

[0014] In the first sealing body, the mounting step of the convex ring mates with the external thread of the first cover connection. Compared to the existing threaded connection that relies solely on thread clearance for sealing, the mounting step provides additional axial positioning support, making the force more even during thread engagement and effectively reducing the risk of leakage due to thread clearance. Simultaneously, the integrated structure of the sealing part and the connection avoids the assembly gaps of separate components, ensuring a more secure seal for the cylinder opening.

[0015] Furthermore, a pressure ring is provided at the boundary between the sealing part and the connecting part, and a first sealing ring is provided between the pressure ring and the mounting step.

[0016] The pressure ring applies a preload to the sealing ring, ensuring a tight fit against the mounting step, forming a composite structure of mechanical restraint and elastic sealing. This fills any minor gaps that may exist in the threaded connection, further enhancing the reliability of the first layer of seal. The pressure ring also applies a preload to the first sealing ring, ensuring a tight fit between the mounting step and the pressure ring's contact surface. This fills any minor gaps that may exist in the threaded connection, improving the stability and sealing durability of the sealing ring and effectively preventing liquid or gas from penetrating from the connection interface of the first sealing body.

[0017] Furthermore, the second sealing body includes:

[0018] The second cover is cylindrical, with external threads on its outer wall and internal threads that match the outer thread on the inner wall of the convex ring.

[0019] An insertion ring is located at the bottom of the second cover.

[0020] The second sealing ring is located at the bottom of the insertion ring and contacts the pressure ring;

[0021] The connecting part and the protruding ring form a slot, and the insertion ring is adapted to the slot and can be inserted into the slot.

[0022] The second sealing body is fitted into the slot of the first sealing body via an insertion ring on the second cover, forming a secondary limiting mechanism: after the insertion ring is inserted into the slot, its bottom second sealing ring comes into close contact with the pressure ring, forming a circumferential seal around the first sealing body. This not only achieves circumferential sealing through a threaded connection, but also enhances structural stability through the axial fit between the insertion ring and the slot, preventing loosening of the seal due to external impacts.

[0023] Meanwhile, the second sealing ring forms a secondary elastic seal on the surface of the pressure ring through the downward pressure of the insertion ring. It overlaps with the sealing area of ​​the first sealing ring to form a double elastic sealing layer. External media must break through the two sealing interfaces one after the other to enter the container. This significantly extends the sealing path compared to the traditional single sealing ring, greatly reducing the probability of leakage.

[0024] Furthermore, the first cover is provided with a contact step, and the second cover is provided with a sealing step that contacts the contact step.

[0025] The contact step of the first cover and the sealing step of the second cover fit together and come into contact with each other when the second cover is tightened. This not only provides stable support for the compression sealing of the second sealing ring and avoids local deformation of the sealing ring caused by uneven force on the insertion ring, but also further restricts the relative displacement between the second cover and the first cover through mechanical contact, preventing the sealing structure from loosening due to external impact or long-term vibration.

[0026] Furthermore, the mounting step is provided with a first groove for fixing the first sealing ring.

[0027] Furthermore, the bottom of the insertion ring is provided with a second groove for fixing the second sealing ring.

[0028] The first slot serves the same purpose in securing the first sealing ring as the second slot does in securing the second sealing ring: fixing the sealing rings. The first slot ensures the first sealing ring is positioned on the installation step, preventing twisting or displacement during thread tightening. The second slot ensures the second sealing ring is positioned at the bottom of the insertion ring, preventing displacement that could lead to seal failure. Both slot structures improve the installation reliability of the sealing rings through positioning. Compared to existing sealing strips that suffer from aging, deformation, and seal failure due to lack of fixation, this design maintains the sealing performance of the sealing rings for a longer period, extending the effective sealing cycle of the container. This is particularly suitable for long-term storage and transportation of coatings. Furthermore, both the first and second covers have protrusions fixedly connected for loosening and tightening.

[0029] The beneficial effects of this application are:

[0030] 1. The dual sealing design, which directly seals the cylinder opening by installing a first sealing body and further seals the first sealing body by a second sealing body, can significantly improve the sealing performance of the container compared to the single thread or snap-on sealing method in the existing technology, and can effectively solve the problem of easy failure of the single sealing structure of the existing paint container.

[0031] 2. In the first sealing body, the mounting step provides additional axial positioning support, making the force more even during thread engagement and effectively reducing the risk of leakage due to thread clearance. At the same time, the integrated structure of the sealing part and the connecting part avoids the assembly gap of separate components, ensuring a tighter seal of the sealing part over the cylinder opening.

[0032] 3. The second sealing body is fitted with the slot of the first sealing body through the insertion ring of the second cover, forming a secondary limiting: after the insertion ring is inserted into the slot, the second sealing ring at its bottom comes into close contact with the pressure ring, forming a circumferential seal on the first sealing body. Not only does it achieve circumferential sealing through threaded connection, but the axial fit between the insertion ring and the slot also enhances structural stability, preventing loosening of the seal due to external impact.

[0037] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0039] The coating container provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0040] Example 1:

[0041] like Figure 1 and Figure 2 As shown in the figure, this application provides a container for coatings, including:

[0042] The cylindrical body 100 has an internal receiving cavity 110 and an opening 120 at the top;

[0043] A cylinder cover, disposed on the cylinder body 100 and used to seal the opening 120, includes a first sealing body 200 and a second sealing body 300;

[0044] The first sealing body 200 is used to block the opening 120, and the second sealing body 300 is used to block the first sealing body 200.

[0045] In some embodiments of this application, such as Figure 1 As shown, the coating container described above employs a double-sealing design: a first sealing body 200 directly seals the opening 120 of the cylinder 100, and a second sealing body 300 further seals the first sealing body 200. Compared to the single threaded or snap-fit ​​sealing methods in existing technologies, this significantly improves the container's sealing performance and effectively solves the problem of easy failure of the single-seal structure in existing coating containers. Compared to the single-layer seal of traditional containers that relies solely on threads or snaps, this double-layer protection system prevents the initial intrusion of impurities with the first sealing body 200, while the second sealing body 300 provides a secondary seal reinforcement to the first sealing body 200. The two layers function independently yet work synergistically, significantly improving the container's ability to resist external moisture, air penetration, and leakage of volatile components from the coating during long-term storage or transportation. Furthermore, a handle is also installed on the cylinder 100.

[0046] Example 2:

[0047] This application provides a container for coatings, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0048] like Figures 1 to 3 As shown, the first sealing body 200 includes:

[0049] A convex ring 210 is provided on the cylinder 100, and an inwardly protruding mounting step 220 is provided on its inner wall, and an internal thread is provided on the mounting step 220.

[0050] The first cover 230 includes a sealing part 231 and a connecting part 232. The connecting part 232 is cylindrical and has an external thread on its outer wall that is adapted to the mounting step 220.

[0051] The sealing part 231 and the connecting part 232 are an integral structure.

[0052] In this embodiment, in the first sealing body 200, the mounting step 220 of the convex ring 210 engages with the external thread of the connecting portion 232 of the first cover 230. Compared to the existing threaded connection method that relies solely on the thread gap for sealing, the mounting step 220 provides additional axial positioning support, making the force more even during thread engagement and effectively reducing the risk of leakage due to thread gaps. Simultaneously, the integrated structure of the sealing portion 231 and the connecting portion 232 avoids the assembly gap of separate components, ensuring a more secure seal of the sealing portion 231 over the opening 120 of the cylinder 100.

[0053] Furthermore, a pressure ring 240 is provided at the boundary between the sealing part 231 and the connecting part 232, and a first sealing ring 250 is provided between the pressure ring 240 and the mounting step 220.

[0054] The pressure ring 240 applies a preload to the sealing ring, ensuring it fits tightly against the mounting step 220, forming a composite structure of mechanical restraint and elastic sealing. This fills any minor gaps that may exist in the threaded connection, further enhancing the reliability of the first seal. The pressure ring 240 also applies a preload to the first sealing ring 250, ensuring it fits tightly against the contact surface of the mounting step 220 and the pressure ring 240. This fills any minor gaps that may exist in the threaded connection, improving the stability and sealing durability of the sealing ring and effectively preventing liquid or gas from penetrating from the connection interface of the first sealing body 200.

[0055] Example 3:

[0056] This application provides a container for coatings, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0057] like Figure 2 and Figure 3 As shown, the second sealing body 300 includes:

[0058] The second cover 310 is cylindrical, with external threads on its outer wall and internal threads that match the inner wall of the convex ring 210.

[0059] An insertion ring 320 is provided at the bottom of the second cover 310;

[0060] The second sealing ring 330 is disposed at the bottom of the insertion ring 320 and contacts the pressure ring 240;

[0061] A slot 340 is formed between the connecting part 232 and the protruding ring 210, and the insertion ring 320 is adapted to the slot 340 and can be inserted into the slot 340.

[0062] In this embodiment, the second sealing body 300 is fitted with the slot 340 of the first sealing body 200 via the insertion ring 320 of the second cover 310, forming a secondary limiting: after the insertion ring 320 is inserted into the slot 340, its bottom second sealing ring 330 comes into close contact with the pressure ring 240, forming a circumferential seal on the first sealing body 200. Not only is a circumferential seal achieved through a threaded connection, but the axial fit between the insertion ring 320 and the slot 340 further enhances structural stability, preventing loosening of the seal due to external impact.

[0063] Meanwhile, the second sealing ring 330 forms a secondary elastic seal on the surface of the pressure ring 240 through the downward pressure of the insertion ring 320, and overlaps with the sealing area of ​​the first sealing ring 250 to form a double elastic sealing layer. The external medium must break through the two sealing interfaces one after the other to enter the container. The sealing path is significantly longer than that of the traditional single sealing ring, which greatly reduces the probability of leakage.

[0064] Furthermore, the first cover 230 is provided with a contact step 400, and the second cover 310 is provided with a sealing step 410 that contacts the contact step 400.

[0065] The contact step 400 of the first cover 230 and the sealing step 410 of the second cover 310 fit together and come into contact with each other when the second cover 310 is tightened. This not only provides stable support for the compression sealing of the second sealing ring 330 and avoids local deformation of the sealing ring caused by uneven force on the insertion ring 320, but also further restricts the relative displacement between the second cover 310 and the first cover 230 through mechanical contact, preventing the sealing structure from loosening due to external impact or long-term vibration.

[0066] Example 4:

[0067] This application provides a container for coatings, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0068] As shown in Figure 3, the mounting step 220 is provided with a first slot 500 for fixing the first sealing ring 250.

[0069] Furthermore, the bottom of the insertion ring 320 is provided with a second slot 600 for fixing the second sealing ring 330.

[0070] The first slot 500 serves the same purpose in securing the first sealing ring 250 as the second slot 600 does in securing the second sealing ring 330; both are used to fix the sealing rings. The first slot 500 ensures the position of the first sealing ring 250 on the mounting step 220, preventing it from twisting or shifting during thread tightening. The second slot 600 ensures the position of the second sealing ring 330 at the bottom of the insertion ring 320, preventing displacement that could lead to seal failure. Both slot structures improve the installation reliability of the sealing rings through limiting their position. Compared to the aging, deformation, and seal failure problems caused by the lack of fixation in existing sealing strips, this design can maintain the sealing performance of the sealing rings for a longer period, extending the effective sealing cycle of the container, making it particularly suitable for long-term storage and transportation of coatings. Furthermore, both the first cover 230 and the second cover 310 are fixedly connected with protrusions for loosening and tightening.
